WARNING
Before normal operation of the shower, it
is essential the following commissioning
procedure is completed correctly.
COMMISSIONING PROCEDURE
The first operation of the shower is intended
to flush out any remaining unit debris and
to make sure the heater unit contains water
before the elements are switched on.
This operation MUST be carried out WITH
the flexible hose screwed to the outlet but
WITHOUT THE SHOWERHEAD ATTACHED.
Make sure the outlet of the flexible hose is
directed to waste.
IMPORTANT: The temperature control MUST
be turned fully clockwise as shown in fig.16;
failure to do this could make the PRD
operate.
• Turn on the water supply to the shower at
the isolating stop valve.
• Switch on the electricity supply to the shower
at the isolating switch.
• Wait until water starts to flow from the
flexible hose.
• Slowly rotate the temperature control fully
anti-clockwise as in fig.17.
• It will take about thirty seconds for a smooth
flow of water to be obtained while air and
any debris is being flushed from the shower.
• When a smooth flow of water is obtained,
turn the temperature control fully clockwise
and anti-clockwise and back again several
times to release any trapped air from within
the unit.
• Once the flushing out has been completed,
switch off the electricity to the shower at the
isolating switch. The water will cease to flow.
• Unscrew the top and bottom retaining screws
again and lift the cover from the backplate.
